Umsetzung im Programm bzw Speicherung im Eeprom:
|
||
|
|
|
||
|
|
Text: einfach rein, alles andere als ESC-Sequenz mit acht bytes (fünf + reserve) speichern
|
||
|
|
|
||
|
|
STYL: ruft eine Druckerfunktion auf
|
||
|
|
<27><s><b><48><32><32><32><32> (Escape, s für style, b für bold (oder u,l,f,s)
|
||
|
|
und asc-zahl, hier bold off
|
||
|
|
<27><s><f><48><50><32><32><32> Font 2
|
||
|
|
|
||
|
|
FEED: ruft eine Druckerfunktion auf
|
||
|
|
<27><f><c><32><32><32><32><32> f für feed, und c für cut (oder p,e,l,b,B,n)
|
||
|
|
|
||
|
|
VARI: sucht entspr. Daten, formt sie im string und schickt sie als Text zum Drucker
|
||
|
|
<27><v><0x35><0x38><32><32><32><32> v für Vari dann zwei Ziffern
|
||
|
|
Variablen werden durchnummeriert von 10..99
|
||
|
|
|
||
|
|
|
||
|
|
Länge: Json Datei max 500byte, dh. sie enthält max400byte text
|
||
|
|
Jeder Textspeicher hat 512 Byte, aber Esc-Sequ braucht 8 byte!
|
||
|
|
Wenn also viele Varis drin sind wirds knapp, aber dann ist die Json ja auch zur Hälfte mit keys gefüllt.
|
||
|
|
Also besser 1k pro Doc vorsehen, Rest immer mit bin-0 gefüllt --->32kB gesamt
|
||
|
|
Dann bleiben noch 32 kB übrig:
|
||
|
|
Abr.-Datensatz je256byte, also Platz für 128DS
|
||
|
|
|
||
|
|
Noch 64kB Reserve, evtl von Master zu verwenden
|
||
|
|
|
||
|
|
(alle settings liegen im int. eeprom)
